In josm-ng, I'm experimenting with multistyle, where each tag can add a (list of) stroke(s) (painting primitives) to apply, and all the tags are processed for given primitive (not ony the first one that matches). This is what would you get for a way with highway=seconday and railway=tram: http://shell.sh.cvut.cz/~nenik/josmng-multistyle2.png Still, one tag can't (easily) influence a stroke based on another tag (like the alpha/dashed painting for tunnels) in my scheme. -- Petr "Nenik" Nejedly, NetBeans/Sun Microsystems, http://www.netbeans.org 355/113 -- Not the famous irrational number PI, but an incredible simulation! _______________________________________________ josm-dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/josm-dev
